I made a post with an outline of our plan:
TLDR - Heinrich Max and Admund go get Julian's cart and start gathering food stuffs and things we'll need to survive the week+ trip to Marienburg (food, tools to fix carts, camping supplies, etc)
Merchant team - Dwarfs can find nice dwarf things to sell, have them boxed in crates. Klaus, Ulrun, Mortus, go find nice carts and things you'll need to sell mercantile goods in Marienburg.
Divide total cost of 2 carts, mercantile goods, and supplies equally 8 ways.
Everyone spends a couple days getting these supplies, and the things they'll need for the long travel ahead. We go over everything we have before we leave, inform the Graf, then start our perilous and exciting journey.
